Propagation & Germination
- Stratification:
- Cold/moist stratification required — 30–60 days
- Germination Time:
- 14–30 days
- Notes:
- Seeds benefit from cold stratification for 30-60 days to break dormancy.
Pre-treatment: Seeds are scarified in a brief, 5 to 10 second hot water bath, then transferred to cold water and left overnight. Seeds that were not imbibed are re-scarified with another hot water bath followed by 24 hr cold water soak. Following scarification, seeds are stratified for 30 to 60 days at 1 to 3 C.
Establishment: Seeds are hand collected in mid August when the capsules turn tan and before they begin to split along the septa. Seeds are gray to brown at maturity. Capsules are collected in paper bags and are spread out in a well ventilated greenhouse. Capsules dehisce forcefully. For efficient seed collection, wrap developing seed capsules in fine mesh bags that allow light transmission when capsules are near maturity. Seeds will be captured in bags as the capsules open.
